JUICE EXTBACTOR.

Application filed June 18,

Our invention has for its object to provide an extremely simple andhighly eflicient device for extracting the juices from lemons, oranges,grape fruitand other citrous fruit and collecting the same afterremoving there from the seeds and pulp.

To the above end, the invention consists of the novel devices andcombinations of devices hereinafter described and defined in the claims.

In the accompanying drawings, which i1- lustrate the invention, likecharacters indicate like parts throughout the several views.

Referring to the drawin s:

Fig. 1 is a view principa y in central vertical section showing theimproved juice extractorattached to t e top of a table;

Fig. 2 is a bottom plan view of the receptacle removed from the base;and

Fig. 3 is a bottom plan view of the uice extractor removed from theoperating sp1ndle.

The numeral 4 indicates a pan-like receptacle having a spindle 5 thatextends axially 25 through its bottom. Said spindle 5 has itsintermediate bod portion expanded to afford upper, interme late andlower annular shoulders 6, 7 and 8, respectively. The lower shoulder 8rests directly on the inside of the bottom of the receptacle 4 and itwill be noted that the body of the spindle 5, between the shoulders 6and 7, is of a diameter less than that between the shoulders 7 and 8.

On the under side of the bottom of the re- 15 ceptacle 4 is a. disk-likebearing plate 9 having an axial hole through which the spindle 5extends. Said bearing plate 9 is pressed onto the spindle 5 withsufficient force to hold said bearing plate thereon and to clamp the 0bottom of the receptacle 4 between the shoulder 8 and bearing plate 9 toform a tight joint and to securely anchor the spindle 5 to saidreceptacle in an' upright position. Formed with the outer edge portionof the bearing 5 plate 9, but ofiset below the same, is an annularmember having punched therein a multiplicity of holes to aiiord a ringgear 10..

Short radial arms 11, formed with the outer edge portion of the ring 10,are riveted to the P bottom of the rece tacle 4 to securely connect saidreceptacle, splndle 5 and ring gear 10 for common rotation.

The receptacle 4 is rotatably and detachably carried by a base 12 byhaving the lower 4 and all the 1926. Serial No. 116,819.

end portion of its spindle 5 mounted in a bushing 13 which in turn ismounted in a bore in said base.

The'bearing plate 9 rests directly on the upper end of the bushing 13and thus supports the receptacle 4 and parts carried thereby free fromthe base 12. The base 12 is formed with the upper jaw of a thumbscrewequipped clamp 14 applicable to the top of a table A. A pinion 15meshing withthe ring 1 gear 10 is secured to a horizontal shaft 16 vjournaled in the base 12 and a bearin 17 on the upper jaws of the clamp14. n the outer end of the shaft 16 is a hand crank 18 by which saidshaft may be operated.

A saucer-like strainer 19 is 'removably mounted on the spindle 5 withinthe receptacle 4 by having at its axis a hub 20 telescoped onto saidspindle between the shoulders 6 and 7 and'supported on the shoulder 7.

A juice extractor 21, which, as shown, is in the form of a corrugatedcone, has an axial hole extending therein from its base adapted toreceive the upper end portion of the spindle 5. The base of the juiceextractor 21 rests on the bottom of the strainer 19 and to hold 30 saidextractor for rotation with the spindle 5, the same is provided in itsbase with a pair of diametrically opposite notch-like seats 22 arrangedto receive the end portions of a pin 23 inserted transversely throughsaid spindle.

Obviously, by operating the crank 18 the receptacle 4 and hence the uiceextractor 21 is rotated by the intermeshing ring gear 10 and pinion 15.From the above description it is evident that the receptacle 4 can belifted from the base 12 which withdraws the spindle 5 from the bushing13 and at the same time disconnect-s the ring gear 10 from the pinion15. It is also evident that the juice extractor 21 may be lifted fromthe spindle 5 and thereafter the strainer 19' can be likewise removedfrom said spindle. By thus mounting the several parts of the juiceextractorthe same may be easily separated for the pa ose of cleansingthe same and very quickly and easily reassembled.

When the device is not in use the receptacle parts carried therein maybe detached from the base and stored away, while said base and the partspermanently attached thereto may be left on the table.

The operation of the device may be briefly described as follows:

A half of a citrous fruit will be held on the :juice extractor 21 andsaid juice extractor rotated by the hand crank 18. The pulp and seedsfrom the fruit will 5 and thereafter the receptacle 4 removed 'spind e'from the base 12 and the juice therein poured into a glass or othercontainer.

The above described invention, while extremely simple' and ofcomparatively small cost to manufacture, has in actual usage provenhighly efiicient for the purpose had in View.

What we claim is: v

1. The combination with a receptacle having a closed bottom and a fixedspindle extending through said bottom, of a clampequip dbase having asocket in which said is removablymounted, a gear on the bottom of saidreceptacle", a crank journaled on said base and having a pinion meshingwith said gear, a juice extractor removably mounted on the spindlewithin said receptacle and held for rotation therewith, and a straineron the spindle under said juice extractor.

' 2. The combination with a receptacle having a closed bottom and afixed spindle extendbe collected 1n thestrainer 19 and the juiceprecipitated therefrom into the receptacle 4. .At the compleing axiallythrough said bottom, a bearing plate secured to the bottom of saidreceptacle and provided with a multiplicity of aperturescircumferentially spaced around said spindle to afiord a ring gear, of aclamp-like base having a bushing in which the lower end portion of saidspindle is rotatably and removably mounted and on which bushing saidbearing plate rests, a crank journaled on said base and having a pinionmeshing with the ring gear, a strainer removably mounted on the spindlewithin said receptacle, and a juice extractor having a socket in whichsaid spindle projects above the strainer and interlocks for detachablysecuring said juice extractor to the spindle for rotation with thereceptacle.

3; The combination with a base, of a receptacle having a closed bottomand a spindle rotatably and detachably mounted on the base, a gear-onthe bottom of the receptacle, a crank journaled on the base and having apinion meshing with the gear and separable therefrom by the removal ofthe receptacle from the base, and a juiceextractor on the spindle withinthe receptacle and held for rotation therewith.

In testimony whereof we afiix our signatures.
